I'm really struggling with this one I keep getting an error message that the word Tree should be the output.

join.py 
def morse_code(word):
    morse_dict = {
        'a': 'dot-dash',
        'b': 'dash-dot-dot-dot',
        'c': 'dash-dot-dash-dot',
        'd': 'dash-dot-dot',
        'e': 'dot',
        'f': 'dot-dot-dash-dot',
        'g': 'dash-dash-dot',
        'h': 'dot-dot-dot-dot',
        'i': 'dot-dot',
        'j': 'dot-dash-dash-dash',
        'k': 'dash-dot-dash',
        'l': 'dot-dash-dot-dot',
        'm': 'dash-dash',
        'n': 'dash-dot',
        'o': 'dash-dash-dash',
        'p': 'dot-dash-dash-dot',
        'q': 'dash-dash-dot-dash',
        'r': 'dot-dash-dot',
        's': 'dot-dot-dot',
        't': 'dash',
        'u': 'dot-dot-dash',
        'v': 'dot-dot-dot-dash', 
        'w': 'dot-dash-dash',
        'y': 'dash-dot-dash-dash',
        'z': 'dash-dash-dot-dot'
    }
class Letter:
    def __init__(self, pattern=None):
        self.pattern = pattern

    def __str__(self):
        morse = []
        for i in self.pattern:
            if i == '.':
                morse.append("dot")
            if i == "-":
                morse.append("dash")
        return "-".join(morse)

class S(Letter):
    def __init__(self):
        pattern = ['.', '.', '.']
        super().__init__(pattern)

Hi! First, your code should be written inside of the morse_code function. Second, you should be translating the word being passed into the function into morse code using the provided dictionary morse_dict. So if the word being passed in is "cat", then the output should be "dash-dot-dash-dot-dot-dash-dash". You'll need to find each letter of the word in the dictionary and then combine the morse code to return it translated.
